ABSTRACT

Objective To develop a new radial artery puncture fixing device to conquer the deficiencies of traditional method. Methods The device was composed of an arm support,a hand support,a wrist part,an arm fixing belt,a palm fixing belt and a tourniquet.The arm support was concave-shaped,and was connected with the hand support with the wrist part.The wrist part had a raised block which was gifted with an inflatable bag.The balloon linked with an inflation balloon with an inflation tube.There was a valve between the inflation tube and balloon.The fixing belt had one end directly connected with the arm support, hand support and wrist part, and the other end linked with the other ends of the above components with Velcro. There was a compression hemostatic balloon at the internal surface of the tourniquet. Results The device behaved well in puncture time and success rate,and decreased the incidence rates of errhysis and hematoma after withdrawing the puncture needle while increased the satisfaction of medical staffs and patients. Conclusion The device gains advantages in simple structure,convenience,practicability and safety,and meets the desired requirements.[Chinese Medical Equipment Jour-nal,2018,39(5)44-46]
